For our overclocking testing, we used AMD Wattman. We maximised the frequency curve, along with the power limit slider, and were also able to set the memory at its maximum frequency of 950MHz. We did all of our manual overclocking testing using the OC BIOS.
Average clock speed under load
This saw our average clock speed rise to 2080MHz, a 6% increase over stock behaviour with the OC BIOS.
Games
As expected, this didn't result in huge gains – Navi doesn't manually overclock too well as we know by now. Still, our 3DMark scores and real-game tests saw improvements between 4-6%, so it's not terrible – it's just not that great either.
